The strange relationship between the Amazon and Australian aboriginal genes

A new Harvard University study published in the journal Nature has found strange genetic relationships between a number of Aboriginal communities living in the Amazon jungle, part of Brazil, with Indigenous people in Australia, New Ghinea and Andaman Islands, in Oceania.

Genetic relationship between the Amazon and Australian aborigines was discovered

According to geneticist Professor David Reich, the project leader, Aboriginal communities with these genetic matches are Suruí and Kariiana, speak Tupí language , and Ge people use language. Xavante.

He affirmed that their ancestral genetic traits were more similar to the indigenous people in the Ocean Islands than any other ethnic group at the present time. However, this similarity is almost negligible in other Native American communities.

Previous genetic studies have shown that Native American communities have spread from the North Pole to the southernmost tip of South America , only from a native population that once traveled about 15,000 years ago. the land is narrow across the Bering Strait, connecting Asia and the Americas (but then disappearing).

In 2012, Professor Reich and colleagues demonstrated that there are a number of Aboriginal groups in Canada carrying DNA traces showing at least two waves of migration from Asia to the Americas after the first wave of the above. .

When expanding this 2012 project, scientists have come up with a new discovery. However, it is surprising that the genetic traits differ from other aboriginal communities in the Americas and cannot be explained by the blending of post-Colombus time , most likely the ancestors of Suruí Aboriginal communities. , Kariiana and Ge are the other migrant groups, coming to the Americas at least as early as the first group to migrate through the Bering Strait./.
